Green video output when using Virtual Camera with Streamyard

[mrwurzal]

Hi Guys so I have just updated to 28 and tried to use my virtual camera over to streamyard but the virtual camera is coming through wwith a green filter over it.

I have tried to google the answer but cannot seem to find anything regarding this issue.

If anyone has any tips to try and resolve this issue would bee much appreciated.

I had the same issue in Chrome with 28.0.2, downgrading to 28.0.1 fixed it. (Log file from 28.0.2).

EDIT: Looks like they've indentified the cause and are working on a fix, until then 28.0.1 works. https://github.com/obsproject/obs-studio/issues/7442

Open OBS Settings -> Advanced -> Video -> Color Range and changing this setting to Limited.

For video streaming, do the following setting

Color Format = NV12
Color Space = Rec. 709
Color Range = Limited

Thank you! I can now work properly again!


Can someone explain why this suddenly became an issue both in Firefox and Chrome? What has changed?

Quote from the fix:

Green tint appears when using converting full NV12 to limited NV12 with
swscale, so just avoid creating scaler by color range for now.
